1，数据源错了，
-(void)adjustProvinceCityFormatByCityId:(int)cId andProvinceId:(int)pId
{
// 找到省份包含的所有城市
self.cityArray = [selfcityArrayByProvinCode:pId];
// 定位具体城市
for (int i = 0;i < self.cityArray.count; i++) {
CommonDistrctInfo *info = [self.cityArrayobjectAtIndex:i];
if (cId == info.idNumber) {
[self.pickerViewselectRow:i inComponent:1animated:YES];//定位pickview,数据源是self.cityarray,而这里用的 mcityArray
currentCityIndex = i;
break;
}
}
// 定位省份
for (int j = 0; j< self.provinceArray.count; j++) {
CommonDistrctInfo *infos = [self.provinceArrayobjectAtIndex:j];
if (infos.idNumber == pId) {
[self.pickerViewselectRow:j inComponent:0animated:YES];//j 在数组里面的索引
currentProvinceIndex = j;
break;
}
}
没有地区时候，做的处理，用省份的第一个，
if (self.cityArray.count == 0) {
CommonDistrctInfo *mInfo = [self.provinceArrayobjectAtIndex:0];
self.cityArray = [self cityArrayByProvinCode:mInfo.idNumber];
}
}
